Connecting device

Abstract

Disclosed is a connecting device. The disclosed connecting device includes a connecting unit whose inside is penetrated and opened and closed according to rotation of a rotor provided therein, and an opening / closing unit that is rotatably coupled to the connecting unit and opens and closes the inside of the connecting unit by rotating the rotor, when being rotated with respect to the connecting unit.

Description

TECHNICAL FIELD[0001]The present invention relates to a connecting device, and more particularly, to a connecting device that connects a plurality of hoses or pipes, and adjusts the movement of a fluid.BACKGROUND ART[0002]A connecting device that is generally applied to connect hoses or pipes corresponds to a device that connects a plurality of hoses or pipes to extend the overall length of the hose or pipe and adjust the movement of a fluid flowing through the connecting device.[0003]In particular, a connecting device that connects fire hoses or pipes is required to connect a long distance from a fire truck to a fire point and supply water in a situation in which the entry of a fire truck to the fire is difficult due to vehicles, various obstacles, and the like at the time of fire fighting, and therefore the connecting device may connect a plurality of hoses each having a length of approximately 15 m to extend the overall length of the connected hoses through which water is supplie...

AI Technical Summary

Benefits of technology

The present invention provides a connecting device that can be used in a moving environment without malfunctions or obstacles. It includes a rotor rotating unit that can adjust the flow rate based on the movement of the opening / closing unit. The device also prevents fluid leakage by utilizing packing or oil rings. Additionally, the device is easy to assemble, repair, and manage due to its detachable coupling of the connecting unit, opening / closing unit, and cap.

Problems solved by technology

In particular, a connecting device that connects fire hoses or pipes is required to connect a long distance from a fire truck to a fire point and supply water in a situation in which the entry of a fire truck to the fire is difficult due to vehicles, various obstacles, and the like at the time of fire fighting, and therefore the connecting device may connect a plurality of hoses each having a length of approximately 15 m to extend the overall length of the connected hoses through which water is supplied.

However, the above-described general connecting device has a problem in that it may be bent against or collide with corners or the like, or the handle may be caught by the corners or the like while being moved in alleys or stairs so that the connecting device may malfunction or the movement of the connecting device may be disturbed.

In addition, in the case of the general connecting device, the water pressure applied to a fire hose rapidly increases when the nozzle of the fire hose is closed, so that the movement and manipulation of the hose becomes inconvenient due to an increase in the weight of the hose, and a hydrant valve or the like should be separately manipulated in order to adjust the hydraulic pressure inside the hose.
